Just thought I'd relay my experience with a similar problem I had. I wasn't able to get into windows
through regular startup or safe mode, it would just blue screen right after the windows loading screen appeared. Also couldn't get into recovery console through the xp cd, it would also blue screen when loading... So I went into my bios
and somehow my SATA HDD mode had been changed from compatibility mode to enhanced mode which apparently doesn't work in my system. Changed it back to compatibility and all is well. I think I cleared my CMOS
by mistake so just a suggestion if you're having a similar problem: Check your bios first!
